.To @ZZ whom t may concern;

Be it known that we, EDWARD HUBER and HENRY M. BARNHART, citizens of theUnited States, and residents of Marion, in the county of Marion andState of Ohio, have inventedV certain new and useful Improvements inCar- Couplings and we do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the` art to which it appertains to make and use the same,reference being had to the accompanying drawings, whichform a part ofthis specication, and in which- Figure lis a longitudinal verticalsectional view of our improved car-coupling, showing it ready forcoupling.

showing it coupled. Fig. 8 is a similar view `showing the pin drawn upand resting with its point in its recess in the act of uncoupling; andFig. 4t is a cross-section on line x x, Fig. 2.

Similar letters of reference indicate corre-` sponding parts in all thegures.

. Ourinvention has relation to that class .of automatic car-couplingsinwhich the pin ,when uncoupled, is supported by a projecting lip upon aspring-block,'sliding in the recess in the draw-head and adapted to bepushed back by the coupling-link; and it consists in the improvedconstruction and combination of parts of, such a coupling, in which theperforation fr the coupling-pin has 'a recess at its upper end for thereception of the point of the pin, and in which the spring-block has anupwardly-projecting lip sliding ina longitudinal slot in the draw-head,guiding lthe block and pushing the pin out of its recess when forcedforwardby the spring, as hereinafter more fully described and claimed.

In the accompanying drawings, the letterA indicates the draw-head, whichis of the usual construction, having the usual vertical perfoi ration,B, forthe reception of the pin C, while its recess D is extendedrearward, forming a perforated bearing, E, in which therearwardly-extending bar F of the sliding spring-block Gr slides,` andagainst which the rear end of aspring,II, wrapped around the bar, bears,

the forward end of which spring bears against rear side of the block,forcing it forward.

5o The upper forward edge of. the sliding block Fig. 2 is a similar viewforms a forwardly projecting lip, I, upon which the point of the pinrests when drawn up, and the upper side of the block is provided with alongitudinal upwardly-projecting lip, J, which slides in a longitudinalslot, K, inthe upper side of the recess in the draw-` head. The rearside of .the upper portion of thevertical perforation for the pin formsa l recess, L, inclined slightly rearward with its lower end, and thelongitudinal slot, which is narrower than the recess, enters the lowerend of the same. When the cars are brought closer together foruncolipling, the link will force the spring-block rearward, and the pinmay be raised and placed with its end in the recess, its upper endpointing forward 5'and in withdrawing the link the spring-block willslide forward, pushing the point of the pin forward out of the recesswith the upwardlyprojecting lip, when the point of the pin will4 restupon the forwardly-projecting lip; and

it will be seen that when the link again isA introduced into thedraw-head the sliding spring-blockwill be forced rearward, allowing thepin to drop in the perforation and throughthe link, coupling again. Itwill also be seen that the upwardly-projecting lip will serve as a guidefor the sliding spring-block,

besides serving to push the pointof the pin forward, and that by havingthe recess inthe perforation for the pin the pin may be withdrawn andbeheld in its raised position while the link .is holding thespring-block back,

which cannot be done in couplings of this class having only aforwardly-projecting lip upon the spring-block, which can only hold thepin h raised when the' link is out of the draw-head, consequentlynecessitating the presence of the brakeman at the coupling exactlyatmthe moment when the cars are to be uncoupled.

Having thus described our invention, weclaim-knowingthateouplingshavebeenmade with sliding spring-blocks havingforwardlyprojecting pin-supporting lips-as follows:

rlhe combination of a draw-head having the" usual vertical perforationfor theY pin, pro vided at the rear side of Vits upper portion with arecess, and having a longitudinal vrecess forming a narrower slotv atits upper side,the forward end of the said slot entering the-lower IOOend of the recess in the pin-recevng perfoour own We have hereuntoaffixed ,our signamtion, 2t spring-actuated block having :L fortures inpresence of two Witnesses.
